My question is: what kind of letters would do well in this deck? Type a few that help summon monsters faster, and etc etc..
For those who ask for 3x The Tricky's because he's a cool combo with gusto griff (and almost always I get the two in hand, the eff's griff and that when he is discarted from the hand to the grave he summon a gusto from the deck)
It also has a problem: my deck's with some letters that invoke synchrons very fast, but has duels that impacts my deck, and step two or three duels without a win ....

I would like suggestions for cards that help solve these problems, any help will come in handy.

I duel in dueling network.com, my nick is Lucas Velocity, if you want duel me, PM me k?

Put rising air current for support. Also, and 3 flying kamakiris and 1 simorgh, bird of ancestry. take out the assaults(and if you want put malefics instead).
hope this helps
